1. A bearing obstruction ejector comprising an l'elongated member having means at one `end for attachment to a structure which is to be freed of an obstruction, the said member and the Isaid means having a longitudinal opening.

therethrough, the portion of the opening located in the means being restricted andy another portion of the opening being enlarged to provide a seat for a cartridge; a tubular member remov ably secured to the elongated member; a block.

removably positioned in the tubular member for .engaging with the butt end of a cartridge which is positioned in the rseat in. the elongated member, whereby the cartridge is prevented from movingrearwardly when ired; a Bring pin mov--l ably extending through the tubular member 'and the block, having one end projecting to a point outside thetubular member and its other end normally positioned adjacent the butt end of the cartridge; and spring means for moving the ring y therethrough, one end of said opening being enlarged; a block removably positioned in the enlarged part of the opening in the tubular member, the said block being positioned with one end in engagement with the butt end of the cartridge,

Having described my' invention, what Ig'claim' whereby upon the ring of thecartridge it is prevented from becoming unseated, the said rblock having a longitudinal opening therethrough whichv is aligned with the longitudinal opening of the tubular member; a ring pin located'in the aligned openings of the tubular member and the block, one end being locatedoutside the tubular member; means for preventing the pin from `falling from the aligned openings; and spring 3. A bearing obstruction ejector comprising an elongated member having a threaded male tubul lar itting at one end for attachment to a structure which is to be freed of an obstruction.' theV said member having a longitudinal bore therein. one end of which bore is restricted and communicates with the opening in the itting and the other end oi which is enlarged to provide a seat for a blank cartridge; a tubular member secured yto the elongated member having a longitudinal opening therethrough, one end of said opening being enlarged; a block. removably positioned in the enlarged part of the opening in the tubular member, vthe said block being positioned with one end in engagement with the butt end of a carA tridge positioned in the elongated member,

whereby upon the ring of the cartridge it is prevented from becoming unseated, the .said bloei; having alongitudinal opening therethrough which is aligned with the longitudinal opening of the tubular member; a ring pin located in the aligned openings .of the block and the tubular member, one end of which projects outside the LEON KANDARIAN.
